1. Introduction
The InfinityOne Softphone allows you to make and take calls directly within the InfinityOne user interface and it behaves similar to an E-MetroTel XSTIM or Nortel/Avaya IP (Unistim) phone This guide provides a description of how to use your InfinityOne Softphone. The InfinityOne Softphone is supported across a variety of personal computer and mobile device operating systems. InfinityOne has both a Desktop and Mobile user interface that are recommended for full time telephony use; the Desktop user interface is supported on Windows, OS X (macOS), and Linux. The softphone is also available on the Web interface, although it is recommended for very low usage scenarios as there are many aspects of its operation that are dependent on having the browser window open and easily accessible.
To obtain a list of supported features and usage, see XSTIM Phones User Guide.
